Pfizer and BioNTech Advance COVID-19 Vaccine Strategy With Study Start of Next-Generation Vaccine Candidate Based on Enhanced Spike Protein Design

NEW YORK, NY, USA and MAINZ, Germany I July 27, 2022 I Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced that the companies have initiated a randomized, active-controlled, observer-blind, Phase 2 study to evaluate the safety, tolerability, and immune response of an enhanced COVID-19 mRNA-based vaccine candidate at a 30 µg dose level. This next-generation bivalent COVID-19 vaccine candidate, BNT162b5, consists of RNAs encoding enhanced prefusion spike proteins for the SARS-CoV-2 ancestral strain (wild-type) and an Omicron variant. The enhanced spike protein encoded from the mRNAs in BNT162b5 has been modified with the aim of increasing the magnitude and breadth of the immune response that could better protect against COVID-19.

This is the first of multiple vaccine candidates with an enhanced design which the companies plan to evaluate as part of a long-term scientific COVID-19 vaccine strategy to potentially generate more robust, longer-lasting, and broader immune responses against SARS-CoV-2 infections and associated COVID-19.

BNT162b5 will be evaluated in a U.S.-based study enrolling approximately 200 participants aged between 18 and 55 who have received one booster dose of a U.S.-authorized COVID-19 vaccine at least 90 days prior to their first study visit. Participants will be stratified by the number of months since their last dose of COVID-19 vaccine received prior to entering the study (three to six months or more than six months). The study does not include a placebo (injection with no active ingredient). For more information about this study please visit www.clinicaltrials.govon this link. 

The Pfizer-BioNTech COVID-19 Vaccine, BNT162b2, which is based on BioNTech’s proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.

U.S. Indication & Authorized Use

Pfizer-BioNTech COVID-19 Vaccine is FDA authorized under Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 6 months of age and older. 

Pfizer-BioNTech COVID-19 Vaccine is FDA authorized to provide:

Primary Series

  • A 3-dose primary series to individuals 6 months through 4 years of age

Booster Series

  • a single booster dose to individuals 5 through 11 years of age who have completed a primary series with Pfizer-BioNTech COVID-19 Vaccine
  • a first booster dose to individuals 12 years of age and older who have completed a primary series with Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA)
  • a first booster dose to individuals 18 years of age and older who have completed primary vaccination with a different authorized or approved COVID-19 vaccine. The booster schedule is based on the labeling information of the vaccine used for the primary series
  • a second booster dose to individuals 50 years of age and older who have received a first booster dose of any authorized or approved COVID-19 vaccine
  • a second booster dose to individuals 12 years of age and older with certain kinds of immunocompromise and who have received a first booster dose of any authorized or approved COVID-19 vaccine

COMIRNATY® INDICATION
COMIRNATY® (COVID-19 Vaccine, mRNA) is a vaccine approved for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 12 years of age and older.

  • COMIRNATY® is administered as a 2-dose primary series

COMIRNATY® AUTHORIZED USES
COMIRNATY® (COVID-19 Vaccine, mRNA) is FDA authorized under Emergency Use Authorization (EUA) to provide:

Primary Series

  • a third primary series dose to individuals 12 years of age and older with certain kinds of immunocompromise

Booster Dose 

  • a first booster dose to individuals 12 years of age and older who have completed a primary series with Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY®
  • a first booster dose to individuals 18 years of age and older who have completed primary vaccination with another authorized or approved COVID-19 vaccine. The booster schedule is based on the labeling information of the vaccine used for the primary series
  • a second booster dose to individuals 50 years of age and older who have received a first booster dose of any authorized or approved COVID-19 vaccine
  • a second booster dose to individuals 12 years of age and older with certain kinds of immunocompromise and who have received a first booster dose of any authorized or approved COVID-19 vaccine

Emergency Use Authorization 
Emergency uses of the vaccine have not been approved or licensed by FDA, but have been authorized by FDA, under an Emergency Use Authorization (EUA) to prevent Coronavirus Disease 2019 (COVID 19) in individuals 6 months of age and older. The emergency uses are only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of the medical product under Section 564(b)(1) of the FD&C Act unless the declaration is terminated or authorization revoked sooner.

INTERCHANGEABILITY
FDA-approved COMIRNATY® (COVID-19 Vaccine, mRNA) and the Pfizer-BioNTech COVID-19 Vaccine FDA authorized for Emergency Use Authorization (EUA) for individuals 12 years of age and older can be used interchangeably by a vaccination provider when prepared according to their respective instructions for use.

The formulations of the Pfizer-BioNTech COVID-19 Vaccine authorized for use in individuals 6 months through 4 years of age, 5 through 11 years of age, and 12 years of age and older are different and should therefore not be used interchangeably. The Pfizer-BioNTech COVID-19 Vaccine authorized for use in children 6 months through 11 years of age should not be used interchangeably with COMIRNATY® (COVID-19 Vaccine, mRNA).
